Title: Battery
Inventor: TUCK CLIVE DANIEL SIDNEY
IPC: H01M4/134
Filed: 1989-01-04
Abstract: The invention concerns rechargeable lithium batteries and anodes for such batteries and method of making the anodes, and comprises the features: a) the anode may be of a solution type alloy of commercial purity Al with at least one of Mg, Ga, Ca, Si, Sn, Li, Ge and Zn; b) alternatively, the anode may be of a wrought eutetic aluminium alloy containing 3 - 25 volume % of dispersed intermetallic particles of average diameter 0.1 to 2 microns; c) the anode may have been electrochemically alloyed with Li and pre­treated by being subjected to more than one charge-­discharge cycle to improve the initial charge-discharge efficiency of the battery. When used as anodes in rechargeable lithium batteries, the specified alloys show high charge-discharge efficiency. Alloys based on commercial purity Al are easier to cut and shape than are alloys based on super-purity Al.

Abstract: In accordance with illustrative embodiments disclosed herein, a formation testing tool suspended in a well on a pipe string includes a valve actuator control system which responds to a command signal having a certain signature. The command signal is applied at the surface to the well annulus, and includes a series of two or more low level pressure pulses which are detected at the downhole tool, each pressure pulse having, for example, a certain peak value which lasts for a certain time. On detection of the command signal, a control system within the testing tool permits selective application of hydrostatic pressure which forces the valve actuator to shift from one position to another, thereby to open or close an associated valve element.

Inventor: SILVIAN SERGIU
IPC: H04B1/04
Filed: 1990-08-01
Abstract: A self-oscillating burst mode transmitter transmits an integral number of cycles of a carrier signal in each transmission burst. Each burst commences at a peak value of the carrier signal and terminates at a peak value. The transmitter includes an L-C tank circuit comprising a transmitting coil (L1) connected to a capacitor (C4). The L-C tank circuit is selectively energized through a switching network (Q1, Q2, U1, U2) connected to a power source, causing the tank circuit to resonate at a prescribed frequency (f₀). Selective energization of the tank circuit is achieved by the switching network as controlled by a peak voltage detection circuit (32, 34). The peak detection circuit senses when a peak voltage is present in the oscillatory waveform appearing across the coil of the resonating tank circuit. Power is switched off to the tank circuit at the conclusion of each transmission burst only when the oscillatory voltage waveform, as sensed by the peak detection circuit, is at a peak. This peak voltage is stored by the capacitor of the tank circuit during the time the power source is not connected to the tank circuit. At the beginning of the next transmission burst, when power is again coupled to the tank circuit through the switching network, the voltage initially appearing across the coil, and hence the voltage at the commencement of the next oscillatory waveform of the transmission burst, begins at the peak voltage value stored on the capacitor.

Abstract: This invention describes a technique for improving the effectiveness of 'poling' of a composite material and hence its degree of electrical activity. The technique utilises a preferential uptake of a polar fluid by one of the phases to reversibly alter the resistivity balance between the materials within the composite. The fluid may be driven off after poling by, for instance, vacuum drying to allow operation of the material as a low electrical loss material.

Abstract: Method and apparatus for improving an efficiency of solution of constraint-satisfaction type problems performed with a digital computer. A method includes the steps of creating a data structure having storage allocated for a plurality of entries, each of the entries having a plurality of attribute fields, including a Binding_set attribute, a Potential_savings attribute and an Accumulated_savings attribute. The method further includes a step of inserting entries into the data structure in response to an occurrence of a failure path identified during a backtrack search of a search tree structure. The method also includes a step of examining the entries of the data structure during a backtrack search in order to avoid paths of the tree structure that are repetitively identified to be failure paths. The step of examining occurs before a forward move from a node of the search tree and determines if a value of a current set of bindings associated with a path from a root node to a current node is already present within the Binding_set attribute of an entry in the data structure. If present, the search backtracks to a father node of the current node thereby avoiding a previously identified failure path.
